Control Registers
The control registers are used primarily to control several banks of FET switches that route clocks and backplane
signals. Please note that certain register settings cause line contention, e.g., setting SWITCH1.4 and SWITCH2.4
both to 0 would drive MCLK with both 1.544MHz and 2.048MHz.
SWITCH1: PIN TO 1.544MHz (OFFSET = 0x0011) INITIAL VALUE = 0xF
